But to Sullivan, the slogan may as well have been the doctor's orders. She even drinks Dr Pepper in the morning.

“People try to give me coffee for breakfast," she told the station. "Well, I’d rather have a Dr Pepper.”

For her 104th birthday, Sullivan was given a cake shaped like a can of of Dr Pepper and plenty of soda, along with a gift basket from Dr Pepper Snapple Group CEO Larry Young.

The retired math teacher gets around with the help of a cane, but still lives in her Fort Worth home. Last year, after her 103rd birthday, Sullivan told the Fort Worth Star-Telegram that she thought people would want to die by the time they reached their 80s or 90s. Instead, she found herself having more fun than ever once she hit 90.

Sullivan said at the time that her medications were limited to a single pill a day. She didn't say what she used to help swallow it, but it would be fitting if it were one of her three daily Dr Peppers.
